To all whom it may concern: I

Be it known that I, GEORGE LITTLE, of RutherfordPark, in the county of Bergen and State of New Jersey, have invented and made a certain new and useful Improvement in Automatic Telegraph Instruments; and I do herebydeclare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawing, making part of this specification, wherein Figure 1 is an elevation of the said apparatus or instrument. Fig. 2 is a plan of the same below the line was, Fig. 1. Fig. 3 is a vertical section of the motor and otherportions of the instrument, and Fig. 4 is an in verted plan of a portion of the motor employed by me.

Similar marks of reference denote the same parts.

In the drawing, I have shown my automatic telegraph instrument as actuated by an electromagnetic motor; but as the same forms a separate matter of invention, I will only describe it sufficiently to show the connection of the two when introduced in one instrument.

My present invention relates to a means for actuating a strip of paper, and transmitting telegraph pulsations to be employed in giving marks in the same character of instrument when used for receiving the message.

In the telegraph instruments heretofore employed for transmitting by perforated paper, a brush of fine steel wire has been used to penetrate the perforations and close the circuit through the roller.

This brush is apt to become injured by the electricity when in use, and the same is liable to wear or injure the paper. To avoid this I make use of a roller, with an edge of platina or other incorrodible metal, and I apply tension to the strip of paper by means of a brush, beneath which the strip of paper passes. v

In the drawing, a represents the frame; I) and c the magnets; 01, the spindle; e, the armatures, and f the governor of an electro- I magnetic motor, that is applied to give rotation to the shaft to, by means of a wormpinion, o, and gear to, or other convenient mechanism. This motor being a separate matter of invention does not require further description.

-Upon the shaft w is the roller b, and the shaft to is sustained by the cross-bar c, between the columns d e. The column d carries a frame, (1 and roller f that is of nonconducting material, and can be swung into contact with the strip of paper that passes around the roller 12 and between the flanges thereof, so that said paper is fed along by the action of the rollers b and f, and g is a spring, formed and applied so as to act to 21, and a screw, 22, holds the said brush in position when placed, so that it gives the desired pressure upon the paper for detaining the same sufficiently to cause said paper to set smoothly against the surface of the metal roller 12. g

The end of the column e projects beyond the cross-bar c, and carries thearm n for the non-corroding stylus, there being a cylinder of hard rubber, or other non-conducting material, intervening between the end of the column and the cylindrical base of the arm, so as to insulate the arm n.

The connection between the cylindrical base of the arm a of. the stylus and the binding screw 11 is effected by the spring 0, and the binding-screw p is insulated from the column 6', so that the electrical circuit passesfrom A the binding-screw p to to the arm a and stylus, thence to the roller b, and by the bar 0 and column d to the binding-screw p of the line or battery wire. The arm n, carrying the stylus, is made with a joint, 1', so that it can be turned back, and the spring t presses the stylus to the paper.

I make use of a disk-formed stylus, with a platina or other non-corrosive metal edge; and said stylus is held by jaws that slip into the end of the arm a, as shown more particularly in detached views, Sheet 3.

By the use of a disk-stylus injury to the papen is prevented',1tlie meehanismmun's with" tinafon nonv-eorrosi-veedgefln combination with lesspower, and instead ofithestyluswearih gq itlrenzarmznfand liollenvb' as and for the purout rapidly by contact with the paper, the disk poses set forth.
